Structural or Non-Structural - Understand Foundation Cracks

Cracks are a popular topic in the waterproofing industry, and when property owners notice them they could be worrisome. Because they lead to water damage and jeopardize the stability of the foundation, hire a professional to assess your cracks to determine if they are structural or non-structural. However, not all cracks cause structural damage. Some cracks are just a natural sign of aging, but they should never be ignored. Since water follows the path of the least resistance, water can flow through these cracks creating a perfect habitat for mold, mildew and insects. Soil gases such as radon can also enter through cracks, polluting the air in your home.

If you have concrete foundation cracks, they can get worse over time. They can start off as non-structural, allowing water to enter through the crack. If left alone, the water eventually deteriorates the inside of the concrete causing cracks to widen. These cracks can easily be fixed by hiring a foundation repair specialist to apply concrete crack injections into the affected concrete. If water seeps through the crack, polyurethane can seal the leak. For moving cracks, a more rigid epoxy material is used to seal the concrete and hold the crack in place.
